Answer:

0.003.

Step-by-step explanation:

We have been given that Lacey measured a neighborhood park and made a scale drawing. The scale she used was 3 millimeters = 1 meter.

To find the scale factor, we will convert 1 meter into millimeters as:

We know that 1 meter equals 1000 millimeters.

\text{Scale factor}=\frac{\text{Drawing side}}{\text{Original side}}

\text{Scale factor}=\frac{3}{1000}

\text{Scale factor}=0.003        

Therefore, the scale factor of drawing is 0.003.

A job can be done by 30 men in 15 days. How long would it take 10 men to do the same job?​
Vladimir79 [104]

Answer:

5 days

Step-by-step explanation:

This questions involves ratios, the job with 30 men can be done in 15 days, so the ratio from amount of men to amount of days the job will take to complete, it is 30:15. If we had 10 men instead of 30, 10 is one-third of 30, so you have to divide by 3 on each side of the ratio to get your answer.

If we do that we get the ratio 10:5.

Meaning that the 5 is the amount of days needed to be taken in order the complete the job.

Hope this helps!

An engineer on the ground is looking at the top of a building. The angle of elevation to the top of the building is 22°. The eng
Pavlova-9 [17]
Let the distance from the engineer to the base of the building be x, then
tan 22 = 450/x
x = 450/tan 22 = 1,113.79

Therefore the distance from the engineer to the base of the building to the nearest foot = 1,114 feet
